I used my computerized knitting machine to make this QR code (2D barcode) scarf. You can turn any text into a QR code at, and use that image as a pattern for knitting. You need neither Photoshop nor a knitting machine to make this project; they just make it significantly easier. When finished, anyone can take a picture of my scarf and get the information stored in the code as text on their screen, and it’s stylish, too! For more info visit
